1995 ICPI tech spec No. 4 Interlocking Concrete Pavement Institute Revised February 2003 Figure 1. The Roman Appian Way: earlyinterlocking Design of Interlocking Concrete Pavement forRoads and Parking LotsHistoryThe concept of interlocking concrete pavementdates back to the roads of the Roman were constructed with tightly fitted paving unitsset on a compacted aggre-gate base. The modern ver-sion, concrete pavers, ismanufactured with close tol-erances to help ensure inter-lock. Concrete pavers weredeveloped in the Nether-lands in the late 1940 s as areplacement for clay brick streets. A strong, millen-nia-old tradition of segmental paving in Europe en-abled interlocking concrete pavement to spreadquickly. It is now established as a conventional meansof paving there, with some two billion ft2 (200 mil-lion m2) installed annually. Concrete pavers came toNorth America in the 1970 s. They have been usedsuccessfully in numerous residential, commercial,municipal, port and airport paving system offers the advantages of con-crete materials and flexible asphalt high-strength concrete, the units have high resis-tance to freeze-thaw cycles and deicing salts, highabrasion and skid resistance, no damage from petro-leum products nor from concentrated point loads orhigh temperatures.
